A graphics rendering system and method is disclosed, in which color values for certain pixels appearing on the screen may be adjusted to create a blurring effect. A pixel-by-pixel comparison may be used to compare differences in depth, as noted in a depth buffer, and if pixel depths are sufficiently close, the pixel's color may be softened to take into account color values of neighboring pixels.

System for softening images in screen space

A background (sky box) in a video game or other virtual reality environment dynamically changes as a function of a parameter, producing a more realistic display. Luminance-only texture and color texture data are employed to create the background. The color texture data are provided as a lookup table in which one axis of the lookup table corresponds to time or another variable, and the other axis indicates the colors of pixels in the display as a function of the altitude or azimuth of the pixels. The luminance-only texture data are thus modulated by the chrominance values from the color texture data for pixels in the background. Optionally, one of a plurality of two-dimensional color textures can be selected as a function of the variable and applied to the luminance-only texture data.
